PET PEEVE CONTEST 
DEADLINE EXTENDED 
to September 30, 1995 


Is everybody happy? Or vvliat? Here it 
is long after the deadline and there are 
no entries for the Pet Peeve contest 
announced last issue. Is it just that 
summer is here, or are you guys so 
bubbly and happy that you ha\>e nothing 
about which to fume and gripe? Maybe I 
shoulda saved this contest for the winter 
when everyone is cranky and out of 
sorts? For the benefit of new readers 
starting this issue and those old readers 
who misplaced the last issue of the 
WSR, following are the rules and an 
explanation of the contest: 

One of my peeves was voiced on page 1 of last 
issue, under the article, BRASS TACKS & STEEL 
LUGNUTS About the Radio Business. Now I want 
to hear yours, just as bold and brassy, no holds 
barred. There will be a nice prize for each of the 
top five submitters to be judged by Cindy and me. 
Here are the rules, terms and conditions: 

1. Submittals should be 200-400 words (500 the 
absolute maximum), on your pet peeve about 
anything related to the radio busitiess or hobby. 
Keep the language clean, and avoid peeves about 
individuals unless about a scam or rip-off. 
Otherwise, peeves should be about inanimate 
subjects, companies, groups, products, services, 
methods, procedures, hardware/software, etc. 

2. Deadline for receipt of your submittal is 2400-lirs, 
(midnight), September 30. 1995. No exceptions. 

3. Submit legible entries by Internet e-mail, Fido 
netmail, CIS e-mail. Fax. postal mail, or private 
file/message upload on the Hertzian Intercept 
BBS. See the Reference Data box and the 
Masthead above for addresses. 

4. Prizes for each of the five winning entries will be 
a PerCon Corp. Spectrum Lite FCC Freq¬ 
uency Database, Spruig ‘95 Ed, CD-ROM , 
ready to run, easy to use, with nearly 3-million 
records. Requires Windows 3.1/up, 4-Mb RAM. 
Prizes will be sent UPS-ground upon publication 
of the selections so make sure we have a valid 
street address. No shipments to PO Boxes! 

5. Judges' decisions are arbitrary, capricious & final. 

6. Winning names and entries will be published in a 
forthcoming issue of the World Scanner Report , 
but anonymity of authorship is assured for those 
who request it with the entry. 

7. Future hint : Next contest will be like this one 
except about our “ warmest fuzzies " in radio. ©

WHY AIR OUR PET PEEVES? 


Good question. Airing both gripes and 
satisfactions aids and promotes a synergy 
in our mutual attraction: hobby radio. 
Speaking of which, here is a peeve 
expressed by an incognito reader on the 
Internet. Too bad he didn’t enter the 
contest, but get a load out of this dude: 

From: Deflatcna AOL-com Bill, are you ever 
capable of answering a topic without injecting venom 
and insult into nearly every sentence? Despite what 
you think, not everyone is out to get you. 

I read your fastest issue of World Scanner Report, and 
you have three columns in there in which you explain 
that you cannot provide your paying customers with 
the same level of support that other merchants provide 
theirs. The main reason, you say, is that ever 
increasing numbers of people are trying to rip you off. 

I don't know about everyone else, but I paid my $25 
and I expect to get my money's worth. When someone 
doesn't give me what he has committed to delivering, I 
expect to get some or even all of my money back. I 
(and I'm sure that most of your readers too) am not 
out to "take you to the cleaners," as you write in 
WSR, Mr. Cheek). We're decent, upstanding folks- 
maybe just as good as you. 

Let's look at it from my perspective. The current issue 
has three columns devoted to your less than charitable 
views of your customers; it has three columns from a 
lady who says her husband's scanning hobby is A-OK; 
and it has 2.5 columns on computer talk in which you 
say "computers are hear to stay," and "don't buy OS/2 
because it is not well supported around the world," 
other dubious bits of advice. Knock off a couple of 
more columns for the address label, a plea to renew 
the subscription and some other house-keeping kinds 
of stuff. Add it up, and you get 20 columns of good, 
solid info out of a possible 30. If it were one issue, I 
suppose that I wouldn't mind, but it's been that way 
for the last few issues. WSR is becoming less relevant 
and more a platform for Mr. Cheek's personal views 
(I'm sorry, that's not what I paid for). Yet, you've 
already judged that I'm a scam artist and have told me 
as much in print. What hope do I have of getting a 
refund (I don't want one, by the way, I just don't plan 
to renew the subscription). 

The point of all of this rambling is that sometimes, Mr. 
Cheek, you're wrong and the other guy is right. I'm 
not saying that this is the case here-there's a lot to 
argue with in what I've said. But if you're not willing 
ever to concede that you make mistakes or that the 
other guy's point of view is equally valid, don't expect 
me to take you seriously. 

ED: Hey, dude, bite me like a dang snake! 
Your nasty hide-behind-a-screen-name 


message is so pertinent, I thought I’d display 
it here as a textbook example of exactly what 
I meant in last month's Brass Tacks essay. 

1 don 7 know which horse you rode in on, but 
it 5 the exact species that adds to the cost of 
business and results in higher prices for 
everyone, not to mention a bad attitude. I 
answ ered you in great detail on the Internet, 
the following cuts to the chase: 

L_ If you feel you aren 7 getting your 
money's worth, you need only ask for a 
refund of all unsent issues. That has always 
been our policy. I will not, however, sell you 
a book or a stack of back issues so you can 
run down to your office copier and duplicate 
them and then come back whining for a 
refund. Nor will I sell you a kit or do-it- 
yourself part so you can blow it to 
smithereens and then howl for a refund or a 
free replacement. Why should everyone else 
have to pay for your failure? Companies 
who provide that sort of “satisfaction" 
policy* may be doing YOU a favor, but the 
rest of us have to pay for it. You think THEY 
absorb the loss from your stupidity? Ha! 
They make the rest of us pay with higher 
prices; that’s all. 

2 Most radioists of any long standing are 
honest, decent people. Radio has enjoyed a 
fantastic growth over the last few years 
where there are a lot of new people from all 
walks of Life, some of whom don 7 know the 
ropes and don 7 have an honest bone in their 
carcass. Obviously, you don't understand 
how only a small handful of that type can 
break a small business. So, I don 7 care ij 
you understand, aside from running last 
month's article and this reply. I'm not going 
to position myself and my family to be slicked 
and skinned by the sicko slimeballs out there. 

1 mentioned my respect for and appreciation 
of our long time clients who were not 
included in that categorization. Either you 
didn 7 catch that or you 're one of those from 
whom my family and I need protection. 

2 Your assertion of my “dubious advice " is 
certainly your opinion and you 're welcome to 
it. But I stand on the advice that OS/2 is not 
a very good operating system for radio 
hobbyists, especially entry level types and 
even most journeymen computists. There is 
no widespread support for OS/2 and it is a 
very difficult system to learn. Things that 


9/1/95 - 8:50 AM ~ Page 1 

























work all day long with MS-DOS and 
Windows can and do choke under OS/2. 

4 You said you felt we offered 20 good 
columns out of 30. That is arguable, but 
even supposing it's true, I *d like you to show 
me ANY other magazine or newsletter that 
offers such a HIGH percentage! Personally, 
I think you for the compliment. I wish 
everyone would rate us so highly! I am 
worried about making every issue contain 5 
or 6 columns of interest to each reader! 

£ Soooo, you didn't like Janet Cravens' 
article and a few others? Should I send you 
an advance copy of the WSP each month for 
your personal approval? Ahem, better get 
your wallet open and start fishing out more 
cold cash for that privilege, pal. . 

Wliat makes you think I don't fess up 
when I'm wrong? Or don't concede my 
mistakes? (Check the back issues!) You 
didn 7 cite any examples so I don 7 have the 
foggiest idea of what you 're talking about. 
As far as conceding that “the other guy’s 
point of view is equally valid'', well you got 
a point there. I don 7 concede fallacies and 
horse feathers. Points of view are NOT 
equally valid; they are only points of view; 
nothing more. O.J. Simpson's point of view 
is that he is innocent. So should he be let 
go? Harumph! If you want to think the sk\> 
is chartreuse, that's fine, but I sure wouldn 7 
feel obliged to concede anything, except 
maybe that you 're color blind or weird. 

Your refund is available upon request. 
Meanwhile, if you want any credibility or 
respect from me, use your real name when 
you communicate with me. Otherwise, all I 
see is a snotty, vicious, nincompoop hiding in 
the dark, to whom I will not pretend civility, 
sociability, or respect. You could be a drug 
peddler or a government agent for all I know. 


SCANNER DATABASE 

©1995 Roy D. Schahrer 

_ Reprinted by permission _ 


Here it is, Roy Schahrer’s comprehensive 
database of all scanners ever made (of which 
he is aware.) Last time I published this list 
for Roy was in Vol-2 of my Seamier Mod 
book where about 250 scanners were listed. 
The list has since grown to 527. One reason 
for publishing this fine list is as a public 
service. Another is to solicit your additions, 
corrections, or comments to help keep it 
updated. 

The list should be self explanatory, with only 
four fields of data: brand name, model name 
or number. Programmable?, and number of 
channels. Codes used are Y=yes, N=n<x ?= 
uncertain/unknown. Non-programmables are 
usually crystal controlled. Please send me 
your input which I’ll forward to Roy so he 


can keep the list updated. Hat’s off to Roy 
Schahrer of Tempe, Arizona:

refund. We’re going to talk more about 


computers with lots of “dubious advice”. 
Sorry, I can’t help it. I have a vision. I 
have a dream. My vision and dream do 
not come from a bottle of alcohol or a 
pipeful of smoking dope. I’d bet serious 
money and one of my TurboWhopper 
scanners on my vision being crystal clear 
and the dream coming true. Listen up! 

Radio, as we know it, is almost over. 
The show is wrapping up: the drama is 
in its final act; after which the name of 
the play is going to change. And, hey, 
Bunky, you’re going to have to change, 
too; else take up knitting or hopscotch, 
maybe. You think I’m kidding? I’m not. 
Some fifteen years ago. Ed Bruce sang 

“The Last Cowboy's Song ”. “The end 

of a hundred-year waltz.....” It won’t be 
long before the end of another hundred- 
year waltz. Radio is changing. 

Radio is an analog physical phenomenon 
just like light, heat, gravity, mass, etc. 
The universe seems to be an analog 
entity. Bear with me for an explanation 
of analog and what it means. If you 
were to walk up an inclined ramp, you’d 
be on an analog device. Walk up a set of 
stairs, and you’re on a digital device. 
Continuous, smooth motions, changing 
or stable are analog in nature. Sudden, 
jerky motions are digital in nature. 

A 12” ruler is an analog device between 
0-12". A voltmeter with a needle is an 
analog device. A sundial is an analog 
device. A clock with a smooth, 
continuously moving second-hand is an 
analog device. On the other hand, a 
water clock (timed by drops) is a digital 
device. Morse code is digital in nature. 
So are smoke signals, traffic lights, brake 
lights, turn signals, and “digital” 
watches. multimeters, frequency 
counters, etc....and computers. 

Generally speaking, things of a digital 
nature and those of an analog nature do 
not mix well. You do one or the other, 
but not both. There are exceptions. 

Radio has a few. but only a very few. 
Morse code is one of the best examples, 
which is nothing more than turning a 
radio carrier wave on and off in an 
intelligent pattern. For example, three 
staccato “on-offs” followed by three 
longer “ons-ofTs” and concluding with 
three more staccato “on-offs” generates 
the well-known international distress 
signal: S-O-S: 

• •• rarara ••• Of 


8/31/95 ~ 4:43 PM - The “World Scanner Report” © 1991-95; Volume 5, No 6; Page A 
















In this example there are three states of 
possibility, each of which are used in 
combination with the others to convey 
meaning or intelligence: (1) a short 
burst, (2) a longer burst, and (3) nothing. 
Lest you’re confused, the “nothing” is 
what goes between the bursts, short or 
long. We think of digital as two-states, 
on or off; 1 or 0, yes or no. etc, and it’s 
true, most modem digital logic is two- 
state. It just doesn 7 have to be. 

The RF spectrum from DC to Daylight is 
an analog, physical resource. It is most 
easily used with other analog resources 
like voice. Radio waves and voice go 
together like pizza and anchovies; peanut 
butter and jelly; dogs and fleas. 

But there is a problem. Voice comm is 
grossly inefficient, subject to misunder¬ 
standing, whether by stupidity, noise, 
interference, deafness, or whatever. 
Voice communication is also not very 
secure and it can be very costly. The 
times are changing with economy and 
efficiency being key to the times. 
Everything has to pay its own way, or it 
is likely to be changed or eliminated. 

Radio communications as we know it. is 
right up there on the list for a critical 
view by almost everyone who uses it, 
with exception, perhaps, of we hobbyists. 
If this status quo doesn’t change, we will 
wake up some day to the sound of silence 
on our radios....or a cacaphony of 
shrieks, squeals, howls, static, peeps, 
beeps, tweets, pops and farts. (Hell it f s 
already that wav on CB, right?) Even 
now, you can tune the shortwave and 
scanner spectrums to see what I mean. 
Pure, understandable, interesting, voice 
signals are scarcer each year. No? 

Not that voice radio communication is 
going to disappear altogether; it is not. 
Not in our lifetimes, anyway. But we’re 
going to hear less and less of it. that’s for 
sure. Already, the more interesting 
public safety & business communications 
arc frogging to the 800 MHz trunked 
bands where monitoring with a scanner 
is more difficult and a lot less fun. 

It’s only going to get worse as these 
agencies and users grit their teeth at the 
same old problems of limited range, 
limited intelligibility, and limited access 
to the spectrum. Next stop, DIGITAL !! 

Yes. voice and other forms of comms can 
be digitized and imposed on a radio 
carrier wave. The FBI. DEA. and other 


federal agencies are using Digital Voice 
Processing (DVP) in conjunction with 
the Digital Encryption Standard (DES) 
to throw completely undecipherable 
signals all over the spectrum. Even if 
there were no DES. it would still be 
impossible for most hobbyists to decode 
the signals. 

That’s right. Bunky, you cannot readily 
decode digital voice signals, and for 
many of the same reasons we can’t 
decode Mobile Display Terminal (MDT) 
signals that are coming into vogue with 
our public safety agencies. 

And then there is an emerging analog 
technique called spread spectrum , where 
the signal is all over the band, controlled 
by digital techniques. The hobbyist 
cannot monitor spread spectrum. 

In a word, the world’s radio comms are 
gearing up to move into digital 
teclmiques. most of which are not within 
the capability of the hobbyist to detect 
and to decode. The more this happens, 
the fewer hobbyists will be left in the 
arena and the less devlopment of new 
hobbyist equipment. 

This IS going to happen; it IS happening 
because digital signals are MUCH more 
efficient, thorough, speedier, reliable, 
and less costly to produce than analog 
signals. The change is not going to be 
an overnight tiling, but it is happening at 
a fast rate and scanning, as we know 7 it. 
will be forever changed by the turn of the 
century. We have to change, too. in 
order to keep pace and to stretch our 
hobby interests out there to where the hot 
stuff is happening. 

By and large, this means you have to get 
computerized. You have to anyway, 
because radio isn’t the only focus in the 
digital revolution. It fact, radio is one of 
the last bastions of analog dominance. 
Already, our cars, washing machines. 
VCR’s, and most other electronic 
apparatus are computerized. I expect of 
Edward Crapper’s flush toilet to become 
computerized before long. Little do you 
know....or maybe you do , that a personal 
computer can be interfaced to almost 
anything electronic for easier, faster, and 
less toilsome operation. 

This is where I see our hobby as an 
extension of Life. All of my scanners are 
computer controlled now. and a hell of a 
lot of my work and other pleasurable 
pursuits are computer based. There is a 


LOT of radio related FUN to be had with 
a computer in the background doing 
work that you’d never do on a bet or a 
dare. And the more the radio sendees 
become computerized\ the more you're 
going to ha\>e to , or else take up knitting. 

Therefore, it will become the policy of 
the World Scanner Report to take the 
lead in gently, but firmly guiding the 
hobby community into computer literacy. 
There is no other recourse. We do not 
have a choice. Well, I suppose some 
people clung to their horses and buggies 
for a while after Henry Ford introduced 
his Model A. I guess others insisted on 
telegraph messages even after the 
telephone became a household tool, but 
you get what I mean here? 


HOW TO BUY A COMPUTER 
FOR YOUR SHACK & STATION 


I suppose most any computer will do for 
basic needs around shop and shack, but 
old clunkers and underpowered new ones 
will be a millstone around your neck in 
no time flat. Old and underpowered 
computers may meet a few present needs 
if not too rigorous, but there is almost no 
room for growth if you’re lugging 
around an old clunker. 

A computer that’s bigger and better than 
you are will challenge you to find bigger 
and better uses for it besides keeping up 
the family checkbook and playing stupid 
video games. ( There are a dozen 
computers around my shop , shack , and 
home , and video games are forbidden 
except under rare circumstances!) If 
you already have an old computer, fine; 
use the hell out of it. But if you are in 
the market for a new one, there arc 
certain guidelines that can save you some 
heartache and ulcers later. It is important 
to get equipped and ready for both now 7 
and the future....which means it should 
be adequate for the next 1-3 years. One 
year is fine for those who can make a 
living from their computers; but as a 
radioist and leisure computist, you *11 
want to make sure that new machine is 
good for the next two or three years. By 
that time, it will be outdated and ready 
for lesser important duties 

Stick to IBM/compatible computers, too! 
Amiga and Atari are effectively gone. 
Macintosh is a fine computer, but not 
widely seen or used around the radio 
scene. Old Apples and TI’s are 
worthless. IBM/compatibles only, please!

You need to know how to buy a 
computer with the minimum of what you 
need. The below Computer Buylist is a 
tabulation of all the important aspects or 
variables associated with what you might 
want or should require in a computer. 


COMPUTER BUYUST 


1. Case: desktop, mini-tower, tower 

2. Power Supply: 100, ISO , 200, 250 watts 

3. Motherboard: selectable CPU

30. Microphone 

31. Printer, leaser; Ink Jet: Dot Matrix 

32. Scanner, page handheld, color /B& W 

From the above list, I can verbalize that the 
minimum new computer that you should buy 
is a “ 486DX2/66 in a tower case w/150-w 
power supply: 8-Mb RAM; AMI Bios; 540- 
Mb IDE hard drive and controller; Vesa 
Local Bus (VLB); 128-k cache memory>; 3'A" 
floppy drive, VLB Video Controller w/l-Mb 
RAM, 15" SVGA monitor; two serial ports; 
one parallel port; and an external 28.8-kbps 
Faxmodem” Your operating system should 
be Blndmvs 95, but MS-DOS 6.2x and 
Windows For WorkGroups 3.11 are ok. 

Optionally , but no less important if budget 
permits, you should specify a 2x CD-ROM, 
Soundblaster 16 audio card with decent 
speakers and a microphone. A dot matrix 
printer and a handheld B&W scanner round 
out the serious radioist’s computer warbag. 

Now this list is not hard and fast, mind you. 
It's more of a starting point for those not in 
the know. You’ll soon learn, if vou don’t 


already know, that nothing is hard and fast in 
the computer world. My Buy List is just a 
guideline for those who need a frame of 
reference. There may be some things on that 
list that you know nothing about. If so, don’t 
worry about it. The thing is that if you’re 
buying a new computer, there is no sense in 
underpowering yourself from the onset. 

When you’re green and your computer can’t 
do certain things, you’ll never do them. If 
your computer can do them, but you can’t, 
relax: the day will come when you can. 

You’ll be told how 4-Mb of RAM is all 
you’ll need. Forget it! Modem computing 
requires 8-Mb. You’ll be told you’ll need 
only about 200-Mb of hard drive space. 
Forget it; you need 540-Mb, minimum, and 
1-Gb if you’re smart. They’ll say all you 
need is a 14” VGA monitor. Hall! Make it 
easier on yourself for only a few bucks more. 
Go for 15” Super VGA (SVGA), and a 17” 
size if you can afford it. Shamrock is a good 
economical brand name, but there are others. 

Unscrupulous salespeople will tell you a 
plain serial mouse is all you need. True, 
until you add a modem to the other serial port 
and then you’re stuck for technical reasons 
I’ll not get into here. Instead, insist on a bus 
mouse, either InPort or PS/2. A bus mouse 
does not use a serial port nor the precious 
IRQ 3 or 4. (Techie jargon.) The tiling is, 
computers let you run two serial devices at 
the same time without problems. But radio 
equipment needs one serial port; a modem 
needs one; and if your mouse uses one, 
something’s got to give. That’s why a bus 
mouse is important (but it also works better 
than a serial mouse.) 

Modems. Don’t get suckered into slow speed 
modems under 9600-bps. Time is money, so 
you shouldn’t settle on anything less than the 
new v.34 modems with fax and 28.8-kbps 
speed. Serial ports must be based on the 
16550 UART. The US Robotics Sportster 
v.34 Data/Fax, modem is a good buy and is 
compatible with just about everything out 
there. Whatever you do, get an external 
modem. No sense in using a valuable slot in 
the computer and besides, the lights are 
pretty and there’s more to learn and absorb 
from external modems. Resale value is higher 
and there’s more you can do with them. 

Sound cards for the radioist? ITell yes! 
There are dozens of uses for sound cards in 
radio, the least of which is sound processing 
to extract intelligible audio from noisy 
signals. How about DTMF decoding? 
CTCSS detection? RTTY, AMTOR, FSK, 
and much more are feasible with a sound 
card in your computer. 

Tower cases important? Sure! They’re 
easier to open up and to work inside. Say 
what? Well, you’re a hacker, aren’t you? 
Hackers dig inside their scanners, and they 


may as well dig around inside their 
computers, too. Computers were made for 
hacking; scanners aren’t. A tower case is 
usually roomier and a little better situated for 
the hacker who may or may not bother 
putting the case back on. Yes, there are a 
bunch of things you can add to a computer to 
enhance vour radioing pleasure. A tower 
case makes it a little easier. And if you can 
work inside your computer, you’ll save $$$! 
And you’ll be one bad dude or gal around 
town! There’s not a lot to it, believe me! 

Summarizing, computers and scanners are 
becoming inseparable. For many of us, they 
already are! You may as well buy smart 
when you buy. If you are anti-computer, your 
radio days are numbered. The Information 
Age is upon us, and it takes a computer to 
help with the processing and storing of that 
information. For some of you, this may be a 
formidable concept. For some of us, it is “old 
hat”. But I gotta tell you to get with the 
program if you haven’t already done so. 


HACKER RESOURCES 


Listen up, here’s another resource for you 
kick-butt hackers. 

MECI

MECI appears to be an industrial surplus 
house, like our favored Hosfelt Electronics. 
But these guys are different enough that 
you’ll want to add them to your database. 

MECI seems well stocked with electronic 
components, fabrication materials, electric 
motors, power supplies, fans, wire & cables, 
connectors, specialized transformers, and 
some slick surprises like a 12-v/l-amp DC 
Adapter with 1.2-inm coaxial power plug, 
positive polarity: looks like it will fit right up 
to the PRO-2004/5/6/2035 and other 
scanners with an external DC jack. The best 
part is the price of $6.50 ea or $5.50 ea/5 & 
up. (Cat No: 600-0225).

SORRY WE'RE LATE 


This issue was started back in July and didn't 
hit the mail until the first of September. 
Please accept our apologies. I’m having an 
odd health problem at the same time that a 
stack of other pressing matters came down all 
at once. Priorities had to be shuffled and the 
time to write was not there. I rationalized 
that this is summer when radio traditionally 
declines in interest anyway, so we decided to 
put this issue on the back burner and take 
care of other things. 

This is V5N6 with four more to go for the 
balance of this publishing year. Regardless 
of the delay, we are committed to ten issues 
per publishing year, five per half year, and 
that’s what you’re assured of getting. We’ve 
had a number of calls, letters, and e-mails 
wondering where the WSR was. That’s 
where. But we’re headed back on track and 
expect to be “normal” by the end of the year. 
Thanks for your patience. 


NEW SCANNER PRODUCT 

PAGER DATA SCO PE 


JSoft Technology comes to market with their 
new pager decoder software and hardware. 
(See what I mean about computers ami 
radio?) The Pager DataScope interface 
hardware consists of a shielded cable with a 
DB-9 connector on one end and a Vg" audio 
phone plug on the other end. The DB-9 
connector is filled with micro-electronics! 
The DB-9 goes to the PC's comport and the 
audio plug goes to a jack that you install on 
the scanner somewhere. On the inside of the 
scanner, you run a small shielded cable to the 
NFM Discriminator chip’s audio-out pin. 
That’s it for the work! 

Powered by the PC’s serial port, the Pager 
DataScope accepts low-level Discriminator 
baseband audio signals and converts pager 
data to RS-232C voltage levels. A trimmer 
pot in the interface sets a signal trigger level 
threshhold to minimize errors and to emulate 
commercial pager hardware. 

Once you’ve tuned to a pager signal, the 
Pager DataScope software does all the rest, 
to decode and display pager data, possibly a 
very interesting sideline of scanning. 

I have a Pager DataScope unit to evaluate 
and report on later, but have not had the 
opportunity to get into it yet. My delay 
should not penalize JSoft Technology and 
those of you who are interested in this sort of 
thing, admittedly an exciting avenue of 
scanning that represents how digital 
technology is available to the casual scannist.

prices, contact JSoft Technology, 21414 W.

PROFESSOR PEABODY 
RUMINATES & RAPS.... PRO-2035 


I finally got some time to catch up on my 
letter pile so here’s the poop. My computer 
deal just came through and I am the proud 
owner of a 486DX2-66 with 8 meg o’ ram 
and a nice and big 850 meg hard drive along 
side my old 120 meg drive that I had for 
years. Now granted this system is not a top 
of the line Pentium or whatever but it’s a 
quantum leap up from the 386SX-25 I used to 
run. The speed is oh so nice!!! My buddy 
that I bought the hardware from is running a 
75 MHz Pentium and it is so fast it’s scary. 

I completed the Zeromatic mod and I must 
say it’s a neat and useful mod. Once 1 got the 
dust out of my brain and the fog cleared, it all 
came together. I first realigned the Zeromatic 
circuit in the 2005 after a few r hour warmup 
(no transformer) and then tried it out and it 
works pretty cool. High power intermods 
that are off frequency by more than 3 KHz 
are no longer a problem; they are ignored 
But I disagree semantically with the author 
about it not changing the selectivity of the 
radio. If you look at the radio as a black box 
and you have a switch that makes intermods 
go away by 70 percent lets say, would that 
make an apparent increase in selectivity? I 
think it does by virtue of they no longer break 
squelch and stop the scanning process. 

But anyway it’s neat. A guy out in the 
boonies of the California mountains won't 
see much of a difference, but in a metro area 
such as you and I live in, it is a welcome 
addition. I have the capability to switch in 
either narrow or wide Zeromatic just to 
evaluate each setting and I found that the 
wide setting is about as useful as the off 
setting. So the least parts count and 
maximum effect of the mod is just to use it as 
off or narnnv. 

I had a PRO-2035 in the shop last month for 
an S meter. Autotagger and Extended Delay 
and after cruising thru the radio and the 
service manual, my opinion is that it’s a 
stripped down version of the 2004/5/6 series 
with a lot of the circuitry now done via 
firmware in the MPU. The squelch circuit is 
the most offensive in that while using the 
Extended Delay mod a squelch break hiss 
now comes out of the speaker after the signal 
goes away and the ext delay is on because the 
mute circuit does not shut off the audio as in 
the previous models. More circuitry has to 
be added to replicate the old circuit and have 
the same operation. 

Same deal with the AGC driven S meter. 
The op amp is gone and I had to hunt around 
to find a point in the AGC line that 1 could 
tap olT some voltage and not screw up the 
AGC at all. But the S meter circuit is still 
the same, as the AGC voltage is a descending 
voltage like before but it’s a little higher in 


overall amplitude. The pickoff point is the 
high side of C283 on the main receiver board 
and it’s +.750 volts with no sig and +.600 
volts with full sig. Adding some gain in the 
S meter amp circuit makes for a wider swing 
which the LM3914 likes oh so much. 

I don’t like the operation of the diode 
detected S meter as you can’t see a birdie on 
the meter which affects the AGC and I don’t 
think it’s as sensitive as monitoring the AGC 
line. But I’m a stubborn Swede. Heh, heh 

...Have you ever noticed that the 
UK/Australia models of the 2035 use a 
different MPU with the P/N of GRE9410? 
Their PRO-2035 has full coverage from 760 
to 1300 MHz? I tried to order the 9410 
model MPU from Tandy National Parts but 
the order taker refused to allude to the 
possibility that the alternate MPU could be 
ordered. She called it an export model and 
would not even tell me how to order export 
parts so it soimds like the FCC scared the 
doodies out of the domestic companies. 

My question is, does anyone know how we 
can get in touch with a foreign parts supplier 
of Tandy parts for MPU conversions? 
Changing the MPU is certainly not in the 
category of “ easily modified ’ as you know. I 
just finished an MPU conversion on a BC- 
2500XL and Uniden was happy as a clam to 
sell the older model MPU for a cheap $19 
plus shipping. It took 3 hours to remove, 
clean the area and install and test the new 
MPU. The only problem I had was a tiny 
solder bridge between 2 pins that flaked the 
weather search. Once found, it worked fine 
and dandy as it should. The job was worth it 
as far as my customer was concerned. My 
eyes are pretty good, but a microscope would 
make the job a lot easier. 

I used a 2x eye loupe to check all the pins 
when done and a pencil point tip on my 
soldering club. I only blew one pin land and 
it was easily repaired with a small piece of 
30 gauge wire. 

By the way, I put the Data Tone squelch 
circuit in a 2006 and after a week of 
operation it started to squeal and chirp just 
like in some 2005 model radios. The big 
capacitor addition stopped the problem cold. 
So I will be adding the caps as a precaution 
in all future mods but I just wanted to let you 
know it happened. 

I don’t remember the review of the BC- 
2500XL or the BC-300XL, but the 25(X) is a 
pretty nice radio with a lot of nice features in 
it. Granted firmware is cheap but the RF 
performance was excellent also as I used it 
for a week to make sure the MPU swap was 
solid. Sensitivity was good and the triple 
conversion was helpful in the intermoci 
department. The only gripe was no 
Zeromatic type circuit when in search mode 
as with the Radio Shaft models.

The other groovy thing about the radio is that 
there’s the same display chip as in the 
2004,5,6 radios and you could wire it up for 
operation with full 2-way interface capability. 
It has the UPD7225g for display chip. But 
wiring the board is tough cuz of the 
compactness of design. Well, that’s all the 
poop for now. 

ED Reply: Yo, Prof, how’s it happening? 
We missed you! The world loves you and 
wants you back! Let's have some more of 
your wizardry before radioing dies off and 
goes the wav of the chambermug. I slipped 
’em some wizardry of my omr on page 10 this 
month, but we need yours, too. 

Re your tiew computer, no, a 486DX2/66 is 
not a Pentium, but it’s close enough for most 
practical purposes. You are not at all 
handicapped with it. By the way, I'd suggest 
using that 120-Mb dhve as C:\ with just 
Windows 95 installed on it, and the new 850- 
A fb hard dhve as D: \ for all your data and 
other programs. And yes, I strongly suggest 
Windows 95 now! I have been an official 
Microsoft Beta Tester for Win 95 since May, 
1994, and can attest to its power and 
capabilities for " Where do you want to go 
today? " It ’s worth it! 

I think your comments on selectivity> and the 
Zeromatic Mod are ok so long as you qualify 
that you ’re not talking about IF selectivity\ 
Obviously, the Zeromatic circuit has no 
relation to the IF strip where selectivityr is 
established and set. But I agree, when 
interference is rejected, that is a form of 
selectivity’, eh? 

Re the PRO-2035, it didn't really relegate 
any of the 2006's hardware functions to 
firmware exactly....but the new functions are 
almost all firmware, for sure. In fact, there 
are only minor differences here and there 
between the hardware of the 2006 and the 
2035. The Logic/CPU board was totally 
redesigned, of course, and it eliminated the 
A IITF function altogether. That explains 
your hearing a hiss when the Extended Delay 
goes into action. I dunno how we'd eliminate 
that right off The 2035 also eliminated IC- 
10 in the 2006, that infamous little CMOS 
bilateral switch in the Squelch circuit. The 
PEL circuit differs a little, but looks similar. 
Beware, because the Master Reference 
Oscillator in the 2035 is 12 MIIz as opposed 
to 10 MIIz in the 2004/5/6 series. 

Frankly, the PRO-2035 is not destined for 
fame and notoriety’: it has already been 
replaced by Radio Shack with the PRO-2042, 
but I know little more yet because the local 
stores don ’1 have the new catalogs in stock 
yet. If true, then the PRO-2035 will amount 
to only a bridge between the venerable 
2004 '5 6 series and whatever is to be the next 
great series, perhaps like the PRO-2005 


bridged the gap between the PRO-2004 and 
the PRO-2006, 

.4 lot of people have spoken highly of the. BC- 
2500XLT, so maybe there is something to it 
as a decent scanner. Unfortunately, it’s gone 
now, replaced by the BC-3000XLT. 

I can 7 say for sure, because we ve had no 
requests and done no research, but it looks 
like the CE-232 Scanner/Computer Interface 
could be workable with the BC-2500XLT. 
The 4x7 keyboard and the UPD7225g LCD 
Display chip are certainly compatible 
enough. The Catch-22 is how the Serial Data 
and Command Data are done. Chip Select 
and Clocking are probably compatible, but I 
can't imagine Uniden and GRE having the 
same formats of data flow, and if they're not 
the same, then the BC-2500 data stream 
would have to be decoded and a whole, new 
control program written for the CE-232. If 
that has to be done, then it could not be cost 
effective thanks to little or no demand. I 
wonder if the BC-3000XLT is similar in 
design? At worst, the CE-232 can probably 
be made to serve as a 1-wav controller for 
the BC-2500XLT. I could mite a *.PER file 
for it, if someone (you?) wanted to try\ 

Ummm, what's this about a big difference 
between the diode S-meter and AGC S-meter 
versions? How? AGC is derived through a 
diode at the same place we hang our own S- 
meter diodes. Same source, same diodes. 
Maybe you could look into that for a future 
article or something? 


Hey, good to hear from you again. Prof!

SHORTWAVE ANTENNA NOTES 
From: Larry Gibes, Longmont, CO 

I have a question about shortwave antennas. 
Can I simply make a 1/4 wave loop? Do I 
comiect one end to ground? My radio doesn’t 
have an antenna jack. Is it easy to add one? 

ED: Shortwave is generally defined as 2-30 
MHz. A quarter-wave loop will vary from 
just under 3-ft dia at 30 MHz to about 40-ft 
dia at 2 MHz. Trouble is, a loop will 
function as such only over a very narrow 
band of frequencies, typically about ±10% of 
the frequency’. Loops are not specifically 
grounded, but one end of the loop is 
connected to the shield of the coax while the 
other end of the loop is connected to the 
center conductor of the coax. Again, 
loops are narrow banded and generally not 
idea for shortwave listening unless you know 


what you 're doing and what to expect. For a 
quick and dirty? higher performance antenna, 
just throw up as much wire as you can, as 
high as possible off the ground. 50-100 ft 
usually works wonders for a portable SfV. 

You should be able to add an external 
antenna connector easily enough, depending 
on the radio and a place to put it. Use either 
a female BNC connector or a female 80-239 
connector, chassis-mount for either type. 
Install it. Ensure the shell of the connector 
connects inside the radio to chassis or PCB 
ground. The center lug of the connector can 
be wired to where ever the portable antenna 
or internal antenna is wired. 

An external “Ion gw ire " antenna can also just 
have an alligator clip on its end, that clips to 
the portable antenna, if there is one. 

CTCSS & PL ami OTHER DECODERS 
From: Joseph Shvnn, Toronto, Canada 
Could you have another look at your PL 
Board mod in Volume II of your Scanner 
Modification Handbook. The equivalent of 
your state police up here use a system which 
maintains the carrier after voice is finished; 
locking the scanner with carrier squelch. 

Perhaps a recommendation to resume 
scanning after loss of tone by means of the 
other output of the tone board would help! 
Oh yeah, more pictures of Cindy and less of 
you... 104 Best wishes & regards. 

ED: Just for that, I'm printing a full double 
page spread of mv mug, and no more Cindy! 
I'm better looking than she! © But anyway, 
do you have my CTCSS/PL tone article 
confused with my later Data/Tone Squelch 
module (MOD-44)? There is no relationship 
of PL tones to after-transmission carriers or 
anti-scanner signals. CTCSS or PL tones are 
subaudible precise tones that allow fleet 
supervisors to render mobile radios silent on 
receive except when their own base or other 
mobile units are talking. This prevents the 
working crews from paying attention to other 
companies who share the same frequency. 

On the other hand, V1N10 of the IVSR 
presented my renowned Data/Tone Squelch 
(DSO) that prevents the scanner from locking 
or staying locked onto audible tones, 
computer data signals and other non-voice 
signals. The PRO-2004/5/6 and 2035 
scanners already have SOUND SQUELCH 
that works much the same way except on 
dead or silent carriers. Finally, there is what 
is called the “Toronto MetroMod", a special 
tone decoder that keeps the scanner from 
hearing those anti-scanner tones between 
transmissions. This moil was presented also 
in V1N10. I think one of these two latter 
mods is more to your needs than messing 
with the CTCSS/PL decoder mod. This stuff 
can be mighty confusing, to say the least. 
See VINK) for the gory details..

PRO-2035/CE-232 NOTES 

From: William Shaft. Tinlev Park, IL 

Dear Bill, I have decided to interface the CE- 
232 with the PRO-2035. It’s a yet to 
accomplish task for me, but I have the service 
manual and one for my PRO-2004. 

Finding out Bill Cheek and his electronic can 
do's has helped me a lot. I have no electronic 
background and everything I learned was 
from books and trial & error . I did learn 
how come from every mistake. 

My First kit was a one tube radio in a 
cardboard box with a piece of plywood in the 
bottom to mount parts 22.5 B + 1 1/2 volt 
power and modification instructions to 
convert it to a two tube shortwave receiver. I 
spent a lot of time past my bedtime listening 
to the ham bands through my Western 
Electric headphone. 

I enjoyed your last copy of the WSR. You 
had the last persuasion I needed to convince 
me to retire with a 30-yr pension from a steel 
mill (at 53-yrs old) and never want a serious 
job again. I have my health and my brain and 
am going from there. Sincerely. PS. Thanks 
for your help and wisdom. 

ED: Well, I hope any influence I had was to 
yon doing something meaningful, fun, and 
profitable! I got a philosophy, Willie, that 
the Good Lord comes around now and again 
just looking for volunteers, kind of like my 
old Chief used to do back in the Navy. He 'd 
come in and pick people who weren't busy 
and haul 'em off for who-knows-what. But 
he'd leave the busy ones the hell alone. I 
figure the Good Lord is a lot like that old 
Chief. Ya never know when he's gonna come 
calling, but if he's got a choice, I reckon 
he'll pick those who don't have anything 
much to do. Hey, if we 're busy on something 
good, then he 'll leave us be, if he can. 


So, whatever you do, don't lay around and 
look like you ain't got anything to do. 
Besides, the missus won 7 take a shine to you 
waliering around underfoot all the time. You 
find yourself something needful and fun to do 
for your T d 30-yr career, if you know what's 
good for you. Something that makes people 
happy would be about right. Am I wrong? 

Now what I want to know is where did you 
get that Western Electric Headphone? 
When I was a kid, I got mine from phone 
booths. All ya had to do was unscrew that 
earpiece and help yourself. Same with the 
mouthpiece for that matter. They were free in 
those days. You could even get a whole 
handset if you wanted it, but my Ma knew 
what those were and disallowed 'em. She 
didn 7 know about the mouthpieces and 
earpieces, though. 

We are now including instructions and 
software for the PRO-2035 as standard in all 
CE-232 Kits. All Kits sold after 9/1/95 will 
have program module and full instructions 
for the PRO-2004/5/6 and PRO-2035 at no 
extra cost. 

For upgraders, we can provide the latest CE- 
232 Program Dusk-Only with Supplementary 
Instructions Software for the PRO-2035 for 
handling costs of $14.95, ppd. The Disk- 
Only contains full software and an ASCII 
textfile manual for the PRO-2004/5/6/2035. 
Printed instructions for the PRO-2035 will be 
included with the Disk-Only, only upon 
request. The full, printed CE-232 Manual 
remains unchanged at $25, deductible 
against an order placed within 30-days. The 
CE-232 Developer's Kit (3 rd party> 
programmer clues & hints) is FREE from the 
BBS as filename: CEDEIELP.ZIP or $29.95 
ppd, as a disk & laser printed booklet. These 
offers are standard and available to all now. 


WSR & MAGAZINE ON DISK? 
From: Raymond Reese, Bremerton, WA 

Called to suggest we incorporate the WSR 
into an electronic MAGAZINE ON DISK. At 
the very least put particulars of what it would 
take, cost, etc. in next issue and let the 
readers decide...(What a Great Idea). 1 ! Chidij) 

ED: Oh nooooo that's not a great idea. 
With the HSR on-disk, our work would be 
copied and spread around the world within 
24-hrs by unscrupulous people who have no 
regafd for copyrights. Enough of my work 
appears around the Internet as it is. I admit, 
it would be nice if we could do that. And 
maybe the day will come when we can. Right 
now, I don 7 know exactly how to do it and 
still protect our rights, but more importantly, 
I don 7 know how to do it and present all the 
graphics and photos in a format universally 
acceptable to all. The idea is under 
consideration, but don 7 look for 
implementation any time real soon. 

BC-855XLT TALK ~ 

From: Alan Gorsuch, Homestead, FL 

I don’t expect an answer to this, but I just 
wanted to let you know that I modified my 
BC-855XLT (date code: OKIB) by the 
instructions on pi 47 of The Ultimate Scanner 
and that both mods, cellular restoration and 
memory upgrade, worked perfectly. 

Cellular restoration is hardly worth the 
trouble because the image rejection of this 
receiver is so poor that a large chunk of the 
cellular band can be heard anyway. It comes 
through loud and clear in the 894 to 916 MHz 
range, 21.7 MHz above the actual frequency. 
I have bought two other BC-855XLTs for 
gifts and they had the same design defect. I 
don’t listen to the cellular band, so consider 
this to be of technical interest only. The 
memory upgrade from 50 to 100 channels is

well worth the price of the book. Keep up the good 
work. I hope to see future books from you. 

ED: Oh, I suppose there will be wore books, but 
right now I aw waiting for feedback frow people as 
to WHAT KIND of books they want. Frankly, the 
out and out modification/hack books have seen 
better days, I think. Scanners are going over to 

firmware and simply cannot be hacked. Eve been 
thinking of doing detailed hack wanuals for specific 
scanners, but no one has given we any input to 
speak of, so I ’w hanging high and dry. 

The BC-S55XLT is an exawple of what's not 

possible anymore . today’s scanners cannot be 

hacked for either cellular coverage nor for wewory, 
except for a decreasing few. 


SUPER-SNOOP MICROPHONE! 


Here is a wicked little tape recorder tool for situations 
where the built-in microphone just doesn't pick up all 
the sounds that you want. My little (and I mean tiny) 
preamplified microphone will tum your deaf tape 
recorder, audio amplifier or other listening device into 
a set of "ears" so sensitive that it will pick up the 
sound of a pair of frolicking gnats at 50-feet! My 
Super-Snoop-Mic permits a tape recorder to clearly 
detect even a faint whisper in a fair sized room. The 
output of my Super-Snoop-Mic can be fed into an 
earphone amplifier or any audio device for 
exceptional sensitivity and fidelity. In fact, this puppy 
can serve as a cheap hearing aid for all sorts of low- 
level audio needs! If is especially suited for 
government operatives, eavesdroppers, private dicks, 
students, and hobbyists who need better recordings! 

Build your Super-Snoop-Mic on a small piece of perf 
board, or as I did. point-to-point without a board! A 
#18 stiff copper wire (ground) can form the backbone 
structure of the assembly. Use your imagination to 
create the housing. I used Radio Shack's 272-340 
mini lamp holder with the lamp holder guts removed, 
to hold everything including the electret Mic element 
and the Gain Adjust trimmer potentiometer. 

You might do better or worse with another design, 
but be creative: build it into a pen. cigarette lighter, 
or something equally unobtrusive. I modeled one 
unit after a Vietnam surveillance device that looked 
like an animal dropping. This “style” can be 
conspicuously placed, if hiding isn’t possible, because 
no one in their right mind is likely to handle it!

other obstacles and still perform a superb job. It 
sports a voltage amplification factor of 47 or a power 
gain of 33-dB. This might be too much for some 
situations, so a GAIN control is included in the output 
circuit to adjust for exacting needs. Polish off the 
Super-Snoop-Mic with a flexible patch cable, 
preferably shielded mini-coax with a phone plug on 
the end to mate with the audio device of your choice.

There's nothing critical to the circuit but tantalum 
capacitors and precision metal film resistors for R-l, 
R-2 & R-3 will minimize internally generated noise 
and help establish a super low tlireshold of detection! 
Radio Shack has a good supply of tantalum 
capacitors but you might have to go to an electronics 
supply house for the precision metal film resistors. 
Then again, you might find the needed values in 
Radio Shack's PMF resistor assortment package. 271- 
309. Good results can be obtained from the values 
specified in the Parts List, however. 

The Super-Snoop-Mic requires a DC supply of 2.5v- 
3.5v with 3v optimum. I designed the amplifier to be 
powered from the pair of AA batteries in a 
microcassette tape recorder which comprised the 
majority of my needs. You can also use a pair of 
silver oxide, mercury, or other hearing-aid batteries to 
power the unit for a reasonable time; current drain is 
low at 1-ma or so. The Super-Snoop-Mic can be 
readily concealed beneath layers of clothing, and
